Benefits of technology

[0026]According to the exemplary embodiment of the present invention, the color conversion layer and the liquid crystal display including the same have desirable color reproducibility, and thus it is possible to provide improved display quality.

Problems solved by technology

However, use of CCFLs results in LCDs that are excessively large, suffer from low color purity, and have non-uniform luminance.
However, the resulting cost is high.
However, the color reproducibility of white LEDs is lower than that of the three color LED.

Embodiment Construction

[0037]The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

[0038]In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. The various Figures are thus not to scale. Like reference numerals designate like elements throughout the specification. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be directly on the other element or intervening elements may also be present. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.

[0039]All numerical values are approximate, and may vary. All exampl...

Abstract

A liquid crystal display according to an exemplary embodiment of the present invention includes: a display panel, and a color conversion layer coupled to the display panel and having a color conversion layer, where the color conversion layer includes a block copolymer including a first copolymer and a second copolymer, and quantum rods dispersed within the block copolymer. The block copolymer includes a first block structure unit formed by the first copolymer; and a second block structure unit formed by the second copolymer, where the quantum rods is are disposed within either one of the first block structure unit and the second block structure unit.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to, and the benefit of, both Korean Patent Application No. 10-2015-0000728 filed in the Korean Intellectual Property Office on Jan. 5, 2015, and Korean Patent Application No. 10-2015-0078618 filed in the Korean Intellectual Property Office on Jun. 3, 2015, the entire contents of each of which are incorporated herein by reference.BACKGROUND[0002](a) Field[0003]Embodiments of the present invention relate generally to liquid crystal displays. More specifically, embodiments of the present invention relate to liquid crystal displays having improved color reproduction.[0004](b) Description of the Related Art[0005]A liquid crystal display (LCD), unlike a plasma display panel (PDP) or a field emission display (FED), is a non-emissive display device that does not form an image by autonomously emitting light. Rather, it forms images by relying on externally-generated light. Therefore, in the LCD, a backlight unit (BL...
